ROBERT B. KRUEGER, or LIMA, onro LOCOMOTIVE FRAME AND ENGINE SUPPORTINGSTRUCTURE Application filed June 22,

' "Stilloth'er objects are: to provide for a firm tyingtogether of allthe parts involved while atthe same time making provision forr'eadynaccess toithem for the purpose of 1nspecting, taking-down, andassembling; to

"- provide means for mounting the engine structure which serves toreinforce the frame; and to provide cylinder-supporting means which willnot interfere with the installation of steam pipes and other elements inthe most convenient manner.

"How these objects and advantages are attained, together with otherswhich are incldent to the invention or which will occur to those-skilledin the art, will appear clearly Y from thefollowing description,reference being had to the accompanying drawings, in which:

Fig-u're'l is a: transverse section through a geared locomotive, lookingforwardly, with certain parts brokena'way and others omitof thelo'comotive), and lower and upper 1928n Serial No. 287,459.

cross-members:5,6, the frame, in turn, carrying a boiler? and cab 8; andit will be seen that, the frameand boiler-are ofiset from thelongitudinal center line of the wheelbase, in order to provide thenecessary space at the right for the mounting of the driving mechanism.

The vertical web of the frame member 4, as clearly shown in F ig; 3, hasa large openingaor cut-out portion, indicated in general bythereferencecharacter "A, to facilitate access to adjacent parts, and to thestaybolts of the firebox-9, and theframe member 3 may, of-course, besimilarlyepertured (in that portion lying adjacent the side ofthefire-box 9 to ,give ready access .to the staybolts. Frame members isbuilt up at topcrand bottom with .flai-i-geseta and 4b. i

7 Along the bottom of theframe member 4; is-secureda.:boXlikestructurelO with diagonal bracing webs 10a, saidstructurehaving a series of innerand outer legsll, 12, forming longitudinallyofthe engineaseriesof gaps 1'3 inwh-ich the usual cranks and connectingrods (not shown) operate (see Fig. 3.) and formingbetween each pair. oflegs .11, 12, a recess 14 (see Fig. 2) to receive a crankshaft bearing,This 1 wholestructure, with its flat longitudinal .-upper face15,-eXt-ends substan tially the full length of the gap A in the sideframe 14, and, is secured "by its integral angular web 16,:1-10111 thebottom of said frame 4, as bolts 17 av reinforcement to the main framealong the bottom of the opening. o Along the top of the frame member 4 Isecure a. bridge-like. angle member 18 having s'tiifening. webs1 9,extending beyond the ends of the gap or opening A, and to this and theframe member ad I secure, as by bolts 20, 21, the angular brackets 22 ofthe supporting structure '23, 24, 25, 26. This supporting structure, ofwhich there is one for each cylinder,- consists of a 'base plate 23, apair of upright crosshea'd guides 24, aydiagonal brace 25 and a head ortop plate'26,-thebase being securedfirnrly, as by'bolts 2'? to the top15 of the structure 10,- and the top plate26' formin- -a base foracylinder'28 which is'secured mg thereto, as bybolts*29. Thediagonalbraces V gaid web thereby serves as 25, together with the webs10a of the structure 10, form a trussed connection between the upper andlower p arts of frame member 4.

The cylinders each carry, laterally, a valvechest 30, and on the back,or the side toward the boiler, each is preferably provided with means,such as the tapped boss 31, whereby it may be secured to the boiler 7 bymeans of a bracket or brace 3s and bolts 3-3, 34. Main steam and exhaustpipes 35 and 36, respectively, may be positioned above and below thebrackets 32 of the several cylinders, lying longitudinally of thelocomotive between the cylinders and chests 28 and 30, on the one hand,and the boiler 7, on the other hand. From these pipes, branches 3?, 88,may connect to the inlets and outlets of the valve-chests. All th sepiping arrangements may be conveniently made, without interference fromthe z-aupporting structure shown.

It will now be evident that the engine construction, including thecylinders with their valve-chests, the cross-head guides, and thecrank-shaft bearing brackets, are rigidly and securely mounted both attop and bottom of the girder frame member s; that the angle structures16 and 22, thewebbed angle bar or bridge member 18, and the truss-likearrange ment of the braces 10a, 25, at the same time give reinforcementto said frame member where it is most needed; and that the foregoingconstruction, in combination with the cross-ties 32, provides a triplesupport for the engines, vertically thereof, to prevent undue bendingstrains on any of the parts, without interfering with the application ofvarious steam piping arrangements.

hat I claim is l. A geared locomotive frame and engine support includinga row of truss-like braces secured at the top and bottom of a member ofthe frame.

2. A geared locomotive frame and engine support including a row oftruss-like braces secured at thetop and bottom of a member of the frameand a bridge member extending longitudinally of said frame member.

3. A geared locomotive frame and engine support including a row oftruss-like braces secured at the top and bottom of a member of the frameand a bridge member extending longitudinally of said frame memberadjacent the juncture of said truss-braces With the top of the framemember.

4. A geared locomotive frame and engine support including a truss-likestructure secured at top and bottom of a frame member and having engineparts mounted thereon, and a support thereabove secured to the engineand the locomotive.

5. In a locomotive having a frame, a boiler, and a row of cylindersmounted laterally of the boiler, a supporting structure for thecylinders secured to the frame at top and bottom,

and a brace between each cylinder and the boiler.

6. In a locomotive having a frame, a boiler, and a row of cylindersmounted laterally of the boiler, a supporting structure for thecylinders comprising a member extending longitudinally of the row ofcylinders and secured along the lower portion of a frame member, and abracing structure for each cylinder including a diagonal member securedto said longitudinal member and to an upper portion of said framemember.

7. In a locomotive having a frame, a boiler, and a row of cylindersmounted laterally of the boiler, a supporting structure for thecylinders comprising a member extending longitudinally of the row .ofcylinders and secured alongthe lower portion of a frame member, and abracing structure for each cylinder including a diagonal member securedto said longitudinal member and to an upper portion of said framemember, together with a brace between each cylinder and the boiler.

8. In a locomotive, an open girder frame member constructed to permitready access to associated parts, and a truss structure extendingacrossthe opening and bracing said member at top and botto 9. In a locomotive,an open girder frame member constructed to permit ready access toassociated parts, and a truss structure extending across the opening andbracing said member at top and bottom, said truss structure serving alsoas an engine support.

10. A reinforcing member, for an open type girder locomotive framemember, formed as an engine and crank shaft sup port.

11. A reinforcing member, for an open type girder locomotive framemember, formed as a crank-shaft support.

12. A supporting structure for the cylinders and crank-shaft of alocomotive comprising crosshead guides and a truss structure connectedtogether.

13. A supporting structure for the cylinders and crank-shaft of alocomotive comprising crosshead guides and a truss struc ture connectedtogether, said truss structure having means whereby it may be mounted onthe locomotive frame.

14. A supporting structure for the cylinders and crank-shaft of alocomotive com prising cross-head guides and a truss structure connectedtogether, said truss structure having means whereby it may be mounted onthe locomotive frame, and serving as a brace therefor. I

15. In combination with an open girder locomotive frame member, abridge-like bracing structure extending generally longitudinally thereofadjacent the opening therein and also serving as an engine support.

16. In combination with an open girder jug locomotive frame member, abridge structure extending longitudinally thereof adjacent the openingtherein and a truss structure extending transversely thereof across saidopening.

17. In combination with an open girder locomotive frame member, a bridgestructure extending longitudinally thereof adjacent the opening thereinand a truss structure extending transversely thereof across saidopening, said structures serving as an engine support.
